Subject resultType="list" contains null values
Date Thu, 20 May 2010 10:57:56 GMT

Hello

I am having the weirdest problem with Ibatis 3. Here is my mapper XML:

   	<select id="verify" resultType="list">
		SELECT table_name.id_column 
		FROM table_name 
		WHERE table_name.other_column = #{parameter_id}
		AND table_name.id_column IN 
		<foreach item="id" index="index" collection="parameter_ids" open="("
separator="," close=")">
			#{id}
		</foreach>
	</select>

Mapper Java looks like this:

    public List verify(
            @Param("parameter_id") Long customerId, 
            @Param("parameter_ids") Long... ids);

The log tells me this:

13:48:11 DEBUG [Slf4jImpl] - <==>  Executing: SELECT table_name.id_column
FROM table_name WHERE table_name.other_column = ? AND table_name.id_column
IN ( ? , ? ) >
13:48:11 DEBUG [Slf4jImpl] - <==> Parameters: 1(Long), 71(Long), 78(Long)>
13:48:11 DEBUG [Slf4jImpl] - <<==    Columns: id_column>
13:48:11 DEBUG [Slf4jImpl] - <<==        Row: 71>
13:48:11 DEBUG [Slf4jImpl] - <<==        Row: 78>
13:48:11 DEBUG [Slf4jImpl] - <xxx Connection Closed>


The query seems to be in order and the result (based on the log) is the
right one. However, the resulting List that I receive from the mapper
contains two null values instead.

Anyone have any ideas what's going on here? 

table and column names have been replaced, please excuse any mistakes
